Ok, we're looking at going boating this summer and I want to take my NIT with me out on the lake. However, I have this unenviable ability to be the first one to take a swim or a fall off the boat, whether I want to or not. So my finding myself in the water is not an if, but a when. (trust me, don't ask.)

So here's my dilemma. 1. I need something waterproof that will still allow me to use my NIT while on the boat, and 2. It needs to float. I expect it to be either in my hands or in my pouch most of the time, but should it go over the side through my general effort at epic klutziness, I want it to stay near the top so I don't have to go scuba diving to get the darned thing.

Any ideas? I've considered using a heavy duty glad quart freezer bag for this, but I'm not sure how well that'll work.
